Ok let's break this down....
The vapor emitted from an e-cig is actually not water vapor, but more like an aerosol gas, as the emissions consist of tiny particles that contain nicotine, glycerin/glycols, artificial flavorings and preservatives, among other chemicals, according to a new study from RTI International.
s. Although some studies have examined the
chemical constituents of e-liquids,3-5 e-liquids are altered
during the heating process and are converted into aerosol and
gases that contain other potentially harmful constituents, such
as aldehydes, polycyclic aromatic hydrocarbons, and metals.4
Aldehyde - Wikipedia, the free encyclopedia
Many fragrances are aldehydes
......
Aldehydes degrade in air via the process of autoxidation.
......
Traces of many aldehydes are found in essential oils and often contribute to their favorable odors
So whatever ejuice they were supposedly testing is not common ejuice....ejuices aren't usually made out of essential oils
but then again essential oils have been long researched and used for medicinal purposes especially in incense...
Polycyclic aromatic hydrocarbon - Wikipedia, the free encyclopedia
PAHs are neutral, nonpolar molecules; they are found in fossil fuels (oil and coal) and in tar deposits, and are produced, generally, when insufficient oxygen or other factors result in incomplete combustion of organic matter (e.g., in engines and incinerators, when biomass burns in forest fires, etc.). PAHs can also be found at high levels[clarification needed] in cooked foods, e.g., in meat cooked at high temperatures over open flame.
So there yet again we are talking about an oil based ejuice, which is not common practice! And tar? There's no tar in ejuice, HOWEVER THERE'S PLENTY OF TAR IN CIGARETTES!
Polycyclic aromatic hydrocarbons are lipophilic, meaning they mix more easily with oil than water. The larger compounds are less water-soluble and less volatile. Because of these properties, PAHs in the environment are found primarily in soil, sediment, and oily substances, as opposed to in water or air.
AGAIN OIL BASED NOT WATER SOLUBLE!
Oh lookie...again, found in cigarettes....
One PAH compound, benzo[a]pyrene, is notable for being the first chemical carcinogen to be discovered (and is one of many carcinogens found in cigarette smoke).
AND METALS??? What metals?
Metal - Wikipedia, the free encyclopedia
The meaning of "metal" differs for various communities. For example, astronomers use the blanket term "metal" for convenience to collectively describe all elements other than hydrogen and helium
you can search for "How To Make Electronic Cigarette Juice" and simply all that it is
1. Nicotine (we all already know about nicotine)
2. propylene glycol (food grade) - Propylene glycol is used as an humectant (E1520), solvent, and preservative in food and for tobacco products, as well as being one of the major ingredients of the "e-liquid" used in electronic cigarettes along with vegetable glycerin. Propylene glycol is also used in various edible items such as coffee, ice cream, whipped dairy products, beer and soda.[7] Vaporizers used for delivery of pharmaceuticals or personal care products often include propylene glycol among the ingredients they are filled with.[4] Propylene glycol is used as a solvent in many pharmaceuticals, including oral, injectable and topical formulations, such as for diazepam and lorazepam which are insoluble in water.[8]
3. vegetable glycerin (food grade) - In food and beverages, glycerol serves as a humectant, solvent, and sweetener, and may help preserve foods. It is also used as filler in commercially prepared low-fat foods (e.g., cookies), and as a thickening agent in liqueurs. Glycerol and water are used to preserve certain types of plant leaves.[9] As a sugar substitute, it has approximately 27 kilocalories per teaspoon (sugar has 20) and is 60% as sweet as sucrose. It does not feed the bacteria that form plaques and cause dental cavities. As a food additive, glycerol is labeled as E number E422. It is added to icing (frosting) to prevent it from setting too hard.
Glycerol is used in medical and pharmaceutical and personal care preparations, mainly as a means of improving smoothness, providing lubrication and as a humectant. It is found in allergen immunotherapies, cough syrups, elixirs and expectorants, toothpaste, mouthwashes, skin care products, shaving cream, hair care products, soaps and water-based personal lubricants. In solid dosage forms like tablets, glycerol is used as a tablet holding agent. For human consumption, glycerol is classified by the U.S. FDA among the sugar alcohols as a caloric macronutrient.
4. Flavorings (food grade) - same as what is used to make candies
